there are a couple of things, first make sure there are not restriction in the exhaust, i know the dealer has had to replace converters under warranty because of this problem, then theres a reflesh program for the computer due to this problem, and lastly,run with egr off make sure it clean of carbon,carbon gets stuck in pintle sets check eng lightbut carbon then blows by so when you remove egr you see nothing, well start with these good luck.

Hello you must disconect battery while replaceing this parts.This is a saftey messure also it alows the computer to reboot once conected and will reset the engine light and put it out for you.If you did not disconect the battery chances are you will still have service engine light on.Disconect your battery wait a couple of minutes reconect that should do it for you .Hope my support helped you.regee

On most vehicles, the sensors are screwed in to the exhaust pipes or exhaust manifolds, usually under the car/truck , in the vicinity of "under the front seat" area. They are usually the size of your thumb, and have a wire going to them.

The evaporative leak detection diagnostic strategy is based on applying a vacuum to the EVAP system and monitoring the vacuum decay rate. The VCM monitors the vacuum level via the fuel tank pressure sensor input. At an appropriate time, the EVAP purge solenoid and the EVAP vent solenoid turn ON, allowing the engine vacuum to draw a small vacuum on the entire evaporative emission system. If a sufficient vacuum level cannot be achieved, a large leak or an EVAP system malfunction is indicated.

First, I wouldn't let that guy work on your car. P1133 is "O2 Sensor Slow Response - Sensor 1" Anybody that has been in the auto repair business for more than a week should know that Sensor 1 is ALLWAYS the FRONT sensor.

Note: O2 sensor codes do not necessarily mean that an O2 sensor needs to be replaced. Most O2 Sensor codes are caused by something other than the O2 Sensor itself. (there are several different possible O2 Sensor codes for your car. P0131, P0132, P0133, P0134, P0138, P0171, P0172, P1133, P1134)

The most likely cause of DTC (Diagnostic TroubleCode) P1133 is contamination of the O2 Sensor. Replacing a contaminated O2 Sensor without repairing the source of the contamination will only result in a repeat repair. It could be caused by bad fuel, improper use of RTV sealant, engine oil or engine coolant. I have seen this caused many times by engine oil leaks that run down the exhaust and clog the holes in the side of the sensor shield. (The sensor must "breathe" to work properly)

Then on the other hand, if your vehicle has a lot of miles on it, the sensor could be just chemically worn out. In any case, the FRONT sensor is the one that is setting the code.

its the O2 Sensor, depending on what bank its on, depends what one needs changed.. bank 1 or A is the sensor on the exhaust closes to the engine, and if its bank 2, or B its the sensor on the exhaust closest to the catalatic converter.... or it could say upstream or downstream, the upstream is the one closest to the engine, the downsream is the one by converter. hope this helps

Which code specifically? Do not assume you need a new solenoid. Our recommendation will depend on the specific code and some troubleshooting results. I usually recommend checking over all the EVAP vacuum lines and the gas cap too whenever there is a purge valve code. Check the vacuum lines at the cannister in the left rear bumper. I will paste info on the purge solenoid below.

Description & Operation
The duty cycle EVAP canister purge solenoid (DCP) regulates the rate of vapor flow from the EVAP canister to the intake manifold. The Powertrain Control Module (PCM) operates the solenoid.
During the cold start warm-up period and the hot start time delay, the PCM does not energize the solenoid. When de-energized, no vapors are purged. The PCM de-energizes the solenoid during open loop operation.
The engine enters closed loop operation after it reaches a specified temperature and the time delay ends. During closed loop operation, the PCM cycles (energizes and de-energizes) the solenoid 5 or 10 times per second, depending upon operating conditions. The PCM varies the vapor flow rate by changing solenoid pulse width. Pulse width is the amount of time that the solenoid is energized. The PCM adjusts solenoid pulse width based on engine operating condition.Removal & Installation
The duty cycle evaporative (EVAP) canister purge solenoid is located in the engine compartment near the brake master cylinder.

Disconnect electrical connector at solenoid.

Disconnect vacuum lines at solenoid.

Lift solenoid slot from mounting bracket for Removal & Installation.

To Install:

Position solenoid slot to mounting bracket.

Connect vacuum lines to solenoid. Be sure vacuum lines are firmly connected and not leaking or damaged. If leaking, a Diagnostic Trouble Code (DTC) may be set with certain emission packages.
